Collected in river Umeälven (and tributary Vindelälven) and Dalälven
Total fecundity available (stripped + dissected). I.e. All eggs are counted!
Also trout data that is filtered out.
Sweden 2 - Swedish west coast
Collected in rearing station in river Göta älv
All fin-clipped individuals.
Only stripped (from what V.T. knows, methods description lacking atm)
Not total fecundity as in Sweden 1
Finland 1
Described in the report “HYDROACOUSTIC ASSESSMENT OF SALMON IN THE RIVER TORNIONJOKI - FINAL REPORT, EU STUDY PROJECT 96-069”
Total fecundity available (stripped + dissected). I.e. an estimation of all eggs!
From river Tornionjoki
Both reared (finclipped) and wild individuals (adipose fin intact) but the majority are wild.
Finland 2
From river Tornionjoki and Simojoki
wild, reared and NA mix of individuals
France
Described in the Samarch report “Changes in sex ratio and fecundity of salmonids” (M. Nevoux et al. 2020, Deliverable D3.3.1)
Methods for assessing fecundity is stripping and a subset of the volume (or weight) of eggs were counted, then the total fecundity was extrapolated based on the total volume (weight) of the stripped eggs (pers. com M. Nevoux)
From 13 rivers in three regions
Origin should mainly be wild (pers. com. M. Nevoux)
The data is filtered in Section 4 when combining data.
2. Spatial aggregations - Baltic Assessment and Atlantic Stock units and Regions
To add spatial information, site name in the data is matched (dplyr::left_join():ed) with site name in the tables created below (SweFin.rivers and French.rivers).
The spatial information added is:
Coordinates (WGS84 DD). French coordinates either provided by Hilaire Drouineau or added manually by V.T., they are at the river mouth (entering the sea or from a tributary) or for the Baie Mont St Michelle in the center of the bay. These are not catch places. For many tributary rivers, the main river mouth is used and for those rivers,the names are changed in 3a when combining data. Swedish coordinates eother existing in the data or added manually (river mouth, not catch place).
Stock unit (for WGNAS stock unit Sweden and France),
Assessment unit (for WGBAST),
Region and genetic region from French regions from Perrier et al. 2011 (doi: 10.1111/j.1365-294X.2011.05266.x), and provided by M. Nevoux, existing in the french fecundity data or added manually by V.T with input from M. Nevoux. Swedish regions are defined as Baltic Sea and Swedish west coast and Finnish is Baltic Sea.

3. Length at age

Keeping only adult individuals (removing NA and 0 sea age individuals).
Remove NA values in length and age.
Remove individuals from Swedish lakes
Remove three mark-recaptured individuals in Swedish data
Remove an obvious outlier in the French data
Correct an obvious outlier in the French data
Calculate total length (\(L_t\)) from fork length (\(L_f\)) where needed in the French data based on the model: \(exp(0.2892351)*L_f^{0.9623479}\) (see below).
The french data has two sources of sex identification (observed in the field vs genetic). I use Genetic sex where available and complete these data with field observations. M. Nevoux considers field observations correct only from (mid) August. From the data where both genetic and field method are available, 14% are incorrect. Keep this in mind if using this info. The sex in Finnish (and likely in Swedish data) is determined visually when gutting the fish and far from all are determined (many NAs).
The kept variables are: length, site, country, origin, year, age_ad, sex. Spatial varaibles are added to the data from the tables created in 2.

4. Fecundity at length
4a. Filter, clean and combine data
Remove NA values in length and fecundity (n.eggs)
Correct an obvious outlier in the Finnish data 1
Calculate total length (\(L_t\))from fork length (\(L_f\)) where needed in the French data based on the model: \(exp(0.05704206)*L_f^{0.99670332}\) (see below).
The kept variables are: length, site, country, origin, year, n.eggs. Spatial variables are added to the data from the tables created in 2.
